* Helm interface
[[https://github.com/tmalsburg/helm-bibtex][helm-bibtex]] is a very cool interface to bibtex files. Out of the box though, it is not super convenient for org-ref. Here, we modify it to make it fit our workflow and extend it where needed.
+Let us add keywords as a searchable field.
+#+BEGIN_SRC emacs-lisp
+(setq helm-bibtex-additional-search-fields '(keywords))
+#+END_SRC
+
+Next, we are going to add keywords to the helm interface. This modifies the helm-bibtex function to add our keywords.
